Good Zones for Testing Dlint Some nameservers are set up to disallow AXFR's by non authorized hosts. What's worse, some of them return _zero_records_ rather than an error! All nameservers USWest has set up for DHCP-serving IP addresses to their customers have this "bug" as of Feb 1998: csh# dig @ns2.uswest.net. 190.225.207.in-addr.arpa. axfr ; <<>> DiG 2.2 <<>> @ns2.uswest.net. 190.225.207.in-addr.arpa. axfr ; (1 server found) ;; Received 0 answers (0 records). ;; FROM: fire.domtools.com to SERVER: 206.196.128.1 ;; WHEN: Sun May 17 01:01:41 1998 csh# echo $status 0 This happens with these servers: ns1.uswest.net. ns2.uswest.net. ns3.uswest.net. ---- earthlink.net. Really huge domain with numerous subdomains. Took >4 hours run-time to lint on a Pentium 166 using a direct 256KB (ADSL) connection to the Internet. vix.com. Really good test zone: weird domains & sub-sub-domains, nonexistent nameservers, multiple levels in 1 zone, etc. wormhole.p-c-net.net. defiant.p-c-net.net. ----
